Impact
If the objects passed in as names to SimpleEval have modules or other disallowed / dangerous objects available as attrs. Additionally, dangerous functions or modules could be accessed by passing them as callbacks to other safe functions to call.
Examples (found by @ByamB4):
Any module where non-underscore attribute chains reach os or sys:
- os.path, pathlib, shutil, glob (direct .os / .sys attributes)
- statistics (has .sys)
- numpy (has .ctypeslib.os and .f2py.sys)
- urllib.parse (has .warnings.sys)
Patches
The latest version 1.0.5 has this issue fixed.
Workarounds
Don't pass in objects or modules which have direct attributes to potentially dangerous items. Use a wrapper to wrap the potentially vulnerable items (See the ModuleWrapper in version 1.0.5)
AnalysisAI
Code injection in SimpleEval when objects with dangerous attrs are passed. PoC available.
